Question About The Tilt Sensor In Guitar Hero Controller
« on: November 12, 2007, 03:46:00 PM »

Ok, here's my problem:
Some times when playing harder fast songs my star power just randomly activates when i am strumming. This is very annoying since it happens when i don't want it to.

What i want to do is, make a switch that can activate or deactivate the tilt sensor, and place a button on the back of the fret board that is linked to the back button to activate star power.

Problem is, i don't know how to deactivate the tilt sensor, and there seems to be no threads about it anywhere.

Any help is appreciated,

Thanks

This is for the X-plorer GH2 Guitar, not the new Wireless GH3 one.

I've been looking at the datasheet for the Accelerometer and it actually has 4 different g-Select (sensitivity) settings, and the board is laid out so any of the 4 can be taken advantage of.

At U5 there are 4 places for Resistors, R28, R29, R30 and R31. From these 4 Resistors (just jumpers really, 0ohms) you can change the sensitivity of the Accelerometer. The way it's setup now is the most sensitive it can be, R30 and R31 in place and for some Guitars it's a bit too sensitive. To decrease it's sensitivity you just change which Resistors are installed in which places.

R30 and R31 in place - 1.5g (most sensitive) - Default setting

R28 and R30 in place - 2g

R29 and R31 in place - 4g

R28 and R29 in place - 6g (least sensitive) - Ya have to REALLY man handle the thing to get SP to go off.


It would also be possible to remove the Resistors completely and install two SPDT switches to open/close the R28 and R29 spots (R30 and R31 are internally pulled low so when the switches are off they would default to being on, same as if the Resistor were in that place so no connections need to be made there at all, but the 0ohm jumper Resistors MUST be removed if this is going to be done) and you'd have access to all 4 of the sensitivity settings, which can be changed on the fly and not hurt anything, and at the max 6g setting it's pretty much disabled really since the speed/force ya have to move it to get it to activate isn't something you'd really be doing in game.

I did some tilt experiments in a xplorer with RDC help...


I've sold that guitar and now I have a Les paul, but I'm clueless

Not sure why this needed to be bumped up from 7 months ago, but since it's here...

The GH3 Wireless Les Paul only has 2 settings, 1.5g (default) or 6g, and at 6g it's not going to be easily set off and may as well be disabled.


Removing the Resistor marked in Red and installing it over to the Blue spot will change the sensitivity from 1.5g to 6g. No Resistor installed in either place is the same as the 1.5g setting.
